FlareSend is a WhatsApp API for developers and businesses. We link a number you already use, then your own systems send OTPs, payment receipts, and customer updates over a REST API.
Updated 12 November 2026
We run the connection between your backend and a WhatsApp number. You create an instance, link the phone with a QR code or a pairing code, and call POST https://api.flaresend.com/send-message. Inbound replies come back to a webhook you host.
Teams use FlareSend for login codes, M-Pesa and card receipts, order and delivery updates, appointment reminders, and paced messages to people who opted in. Plans are flat 30-day prices in Kenyan shillings: Basic is KES 500 for one number, Pro is KES 1,500 for up to five, and Business is custom. There is a 4-day free trial and no per-message fee.
FlareSend is not Meta's official WhatsApp Business Platform, also called the Cloud API, and we are not affiliated with Meta. Linking a number here does not give you a green tick, Meta template approval, or Meta's per-message billing. Those belong to the official platform, usually through a provider. We say so on how it works and on the comparison page.
We also do not move money. When a customer pays by M-Pesa, your payment provider confirms the transaction and your server asks us to send the WhatsApp receipt.
FlareSend is based in Kenya. Support is at support@flaresend.com, and the chat on this site reaches the same team. Billing is in KES through M-Pesa.
